Thank you for summarising the available information, Carl. It is clear that the aircraft with engines running at 1.98 ata were rare. Your remark, that the priority at this time would have been air combat at medium altitudes, is very useful. It would have been relatively sensible to attempt to match the performance of Sptifires and Mustangs at medium altitudes, rather than at higher altitudes, where the Merlin's two-stage supercharger would probably have provided much more consistent performance than the German engines in any case.
Your hypothesis that the Schlachtgruppen in the East consumed almost all available C3 fuel, and therefore it was impossible to use 1.98 ata boost on on Bf 109s, appears well founded to me. There is also the additional consideration that from January, several Fw 190 fighter groups were also transferred to the East, leaving even less C3 available for Bf 109 units. Another, peripheral set of consumers of C3 were the Ju 88 G-1 night fighters of NJG 100.
The document with the title 'Umrüstnummer 63253' was mentioned by the Hungarian Bf 109 enthusiast 'Kurfürst' a week ago on another forum, see
